dune-bs

This is a development setup to explore and experiment around the integration of Dune with Melange bsc compilation tool.

For more context, see: ocaml/dune#140.

Setup

You need Esy, you can install the beta using npm:

npm install -g esy

NOTE: Make sure esy --version returns at least 0.6.8 for this project to build.

Then run the esy command from this project root to install and build dependencies.

Getting started

To keep an incremental approach, the first thing that we're attempting to do is to build an .ml file written for BuckleScript with Dune.

After running esy to download dependencies and build them, run

esy step1

Which will build bin/Hello.ml with dune and bsc (still wip).

We will add more steps with more complex cases over time (with Reason syntax, with ppx, with libraries...).

Local development flow

To develop locally, clone dune repository:

git clone https://github.com/jchavarri/dune
git checkout dune-bs

and add a resolution to this project package.json like:

  "resolutions": {
-   "@opam/dune": "jchavarri/dune:dune.opam#d29d5f4"
+   "@opam/dune": "link:../path/to/dune/dune.opam"
  }
